Njoku shined bright, catching nearly everything thrown his way, during the Browns' initial rookie mini-camp. Rookie quarterback DeShone Kizer might've put it best. "He's a freak," he said. ... Indeed, Njoku, whom the Browns selected with the 29th pick in the 2017 NFL Draft last month, has the potential to be a mismatch problem for opposing defenses as early as this season. As the team's official website put it, "The former national boy's high jump champion is built like a power forward and runs like a track star. ..." Njoku, who was recruited by the University of Miami as a wide receiver and briefly moonlighted at linebacker, caught 64 passes for 1,060 yards and nine touchdowns in just nine starts and 22 games. He's a threat in the vertical pass game and can make defenders miss in open space. All of that was evident at mini-camp, as Njoku -- who clocked a 4.64-second 40-yard dash at 246 pounds -- galloped down the field and weaved through defenders. At just 20 years old, though, he'll admit he's still a work in progress. Redrafters might want to take note of that. Dynasty owners should already have done so.
